The page->flags D-cache dirty state tracking depended upon
NR_CPUS being a power-of-2 via it's "NR_CPUS - 1" masking.
Fix that to use a fixed (256 - 1) mask as that is the limit
imposed by thread_info->cpu which is a "u8".
Finally, add a compile time check that NR_CPUS is not greater
than 256.

unwind.c can read the wrong unat bits from switch_stack.
sw->caller_unat is the value of ar.unat when the task was blocked.
sw->ar_unat is the value of ar.unat after doing st8.spill for r4-7.
IOW, ar_unat is caller_unat with 4 bits changed.
unw_access_gr() uses sw->ar_unat for r4-7 (correct), but it also uses
sw->ar_unat for other scratch registers (incorrect). sw->ar_unat
should only be used for r4-7, everything else should use
sw->caller_unat, unless modified by unwind info. Using sw->ar_unat
risks picking up the 4 bits that were overwritten when r4-7 were saved.
Also this line is wrong
unw.sw_off[unw.preg_index[UNW_REG_PFS]] = SW(AR_UNAT);
and should be
unw.sw_off[unw.preg_index[UNW_REG_PFS]] = SW(AR_PFS);

i386 machine_power_off was disabling the local apic
and all of it's users wanted to be on the boot cpu.
So call machine_shutdown which places us on the boot
cpu and disables the apics. This keeps us in sync
and reduces the number of cases we need to worry about in
the power management code.

Call machine_shutdown() to move to the boot cpu
and disable apics. Both acpi_power_off and
apm_power_off want to move to the boot cpu.
and we are already disabling the local apics
so calling machine_shutdown simply reuses
code.
ia64 doesn't have a special path in power_off
for efi so there is no reason i386 should. If
we really need to call the efi power off path
the efi driver can set pm_power_off like everyone
else.

We only want to shutdown the apics if reboot_force
is not specified. Be we are doing this both
in machine_shutdown which is called unconditionally
and if (!reboot_force). So simply call machine_shutdown
if (!reboot_force). It looks like something
went weird with merging some of the kexec patches for
x86_64, and caused this.

machine_restart, machine_halt and machine_power_off are machine
specific hooks deep into the reboot logic, that modules
have no business messing with. Usually code should be calling
kernel_restart, kernel_halt, kernel_power_off, or
emergency_restart. So don't export machine_restart,
machine_halt, and machine_power_off so we can catch buggy users.

It is no longer valid to not replace instructions, since we depend on
different behaviour depending on CPU capabilities.
If you need to limit the capabilities of the replacements (because the
boot CPU has features that non-boot CPU's do not have, for example), you
need to explicitly disable those capabilities that are not shared across
all CPU's.
For example, if your boot CPU has FXSR, but other CPU's in your system
do not, you need to use the "nofxsr" kernel command line, not disable
instruction replacement per se.
|
|
It's really just a single instruction, conditional on whether the CPU
supports FXSR or not, so implement it as such instead of making it a
function that queries FXSR dynamically.
This means that the instruction just gets automatically rewritten to the
correct one at boot-time.

These days %gs is normally the TLS segment, so it's no longer zero. As
a result, we shouldn't just assume that %fs/%gs tend to be zero
together, but test them independently instead.
Also, fix setting of debug registers to use the "next" pointer instead
of "current". It so happens that the scheduler will have set the new
current pointer before calling __switch_to(), but that's just an
implementation detail.

to user space, we can now access the userspace registers with
reference to the kernel stack using current_thread_info(), rather
than remembering the stack pointer at the time nwfpe was called.
